Massage sandal

ABSTRACT

A massage sandal having a base, a plurality of projections provided on the upper and lower surfaces of said base, and a band fixed to said base, where said projections stimulate the sole of the foot to facilitate the circulation of the blood and strengthen the connective tissue of the sole of the foot by massaging the sole of the foot during the walking of the person who wears it. Therefore, the sandal is good for the health of the foot.

UNITED STATES PATENTS 1 Claim, 4 Drawing Figures 3,100,483 8/1963Altmeyer et al. 128/25 B MASSAGE SANDAL FIELD OF THE INVENTION Thisinvention relates to massage sandals which are comfortable and good forthe health of the body, especially for the feet.

Further the invention relates to the sandals which have a plurality ofwart-like projections on their upper and lower surfaces, and saidprojections stimulate the soles of the feet and facilitate thecirculation system of the blood within the sole of the feet.

Still further, the invention relates to the sandals which can beproduced easily.

BACKGROUND OF THE INVENTION In these modern days, the common run ofpeople have relatively little chances of walking, and it is very rare towalk on the unpaved rough roads. Therefore, the feet of the people arephysically weak, and it will be not to much to say that the peoplesuffer from some kind of disease.

It goes without saying that the most preferable method to keep thehealth of the feet is to walk with bare feet on the natural ground.However, nowadays unfortunately, most of roads are artifical ones suchas those paved with asphalt or concrete, therefore, the walking in thenatural circumstances with bare feet cannot be easily hoped for.

BRIEF SUMMARY OF THE INVENTION In view of the above situation, theobject of the present invention is to provide novel sandals whichimprove the condition of the health of the body, especially of the feet.And pursuant to the above-mentioned object, the sandals of the presentinvention are provided with wart-like projections on their upper andlower surfaces, thereby the wart-like projections of the sandals areclosely contacted with the soles of the feet of the person who wearssaid sandals, and the projections of said sandals give the sense just ashe walks on the natural ground, and further the above-mentioned defectscan be covered up.

Another object of the invention is to provide the sandals in a novelconfiguration which can be produced easily in the commercial scaleproduction processes.

BRIEF DESCRIPTION OF THE DRAWINGS These and other features andcharacteristics of the invention will be more fully understood byreferring to the following detailed description presented solely for thepurpose of illustration and to the accompanying drawings, in which:

FIG. 1 is a perspective view of the sandal of the present invention;

FIG. 2 is a longitudinal cross sectional view taken along the line II IIin FIG. 1;

FIG. 3 is a transversal cross sectional view taken along the line IIIIII in FIG. 1; and

FIG. 4 is also a transversal cross sectional view taken along the lineIV IV in FIG. 1.

DETAILED DESCRIPTION OF THE INVENTION Now referring to the accompanyingdrawings in FIGS. 1 to 4, inclusive, the numeral 1 indicates the base ofthe sandal of the invention. Said base 1 is provided with a plurality ofwart-like projections 2 on its upper surface and similar projections 3on its lower surface.

The configuration of said base 1 is like the plan shape of the sole ofthe foot and the thickness of which is almost equal throughout. Saidbase 1 and the projections 2 and 3 are formed integrally by usingresilient materials such as elastic synthetic resins, synthetic rubberand natural rubber through molding process such as the injectionmolding. As for said synthetic materials, for example, butyl rubber,polyvinyl chloride, polyethylene etc. may be used.

On the portion of the base 1 corresponding to the plantar arch of thefoot, longer projections 2a are provided, and on the heel portion areprovided with shorter projections 2b, and further other remainingportions are provided with projections in medium length. Thereby theface formed by the tips of the projections 2 fits well to the ruggedsurface of the sole of the foot.

While on the opposite side, i.e., the lower side of the base 1 isprovided with a plurality of the projections 3, and the length of eachprojection 3 is equal to that of the projection 2 at the correspondingposition on the upper surface of the base 1. Thus the shapes of theprojections 2 and 3 are symmetric with each other with respect to thebase 1. The base 1 is further provided with a band 4 and a binding metal5.

The sandals of the present invention having the above-explainedconstruction, when such sandals are used, the projections 2 and 3 on thebases 1 of the sandals elastically massage the soles of the feet tostimulate, and relieve the fatigue of the feet and refresh the body andmind of the person who wears them. In addition to that, the sandals ofthe invention facilitate the circulation of the blood in the feet,strengthen the connective tissues of the weak feet, cure the slightlyflat feet, and further stimulate the handy legs or plumpy feet to createthe beauty of leg lines.

Further, the projections on the both surfaces of the base of the sandalin the invention are provided symmetrically with regard to the plane: ofthe base, accordingly, both sandals, right and left, can be formed withusing the same mold, and only the binding metals 5 may be fixed to theproper sides of the bands, respectively. Therefore, the production costfor the sandals can be greatly reduced.

As disclosed in detail in the above, the sandals of the presentinvention comply with the requirements of massage and treatment of thefeet, and by using always the sandals of the invention, anyone canresume the feeling of the bare-foot walking on the natural ground.

It should be emphasized, however, that the specific embodiment asdescribed and shown herein are intended as merely illustrative and in noway restrictive of the invention. j

I claim:

1. A massage sandal which comprises in combination,

A. a base of said sandal with the shape of the periphery of the sole ofthe foot;

B. a plurality of projections provided on the upper surface of said basein which each length of said projections corresponding to the concaveportion of the sole of the foot is long and each length of saidprojections corresponding to the convex portion of the sole of the footis short;

C. a plurality of other projections provided on the lower surface ofsaid base in which each position of said other projections is symmetricto each of said projections on the upper surface with regard to saidbase and each length of said other projections is the same as the lengthof each corresponding projection on said upper surface of said base; and

D. a band fixed to said base of said sandal.
